Which of the following results in the difference of two squares? a. (4x-5y)(4x+5y)
b. (5x+3y)(5x+3y)
c. (2x-3y)^2
d. 4x^2(3x-9)

The answer is a.

Step-by-step explanation:

Observe the formula:

A is the only one that has this format. Thus, it is the difference of two squares.

area = length x width

length = 2 x width

32 = 2 x width x width

32 = 2 x width^2

36 = width ^2  

width = 6

length = 12

area is 32

perimeter = 2 x 12 + 2 x 6 = 24 + 12 = 36

hello from mrbilldoesmath!

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.
